# Pico-Game-Controller
|
|
|
|
WIP code for a rhythm game controller using a Raspberry Pi Pico. Intended for SDVX or IIDX but is capable of handling 11 buttons, 10 LEDs, 1 WS2812B RGB strip, and 2 encoders.
|
|
|
|
Demo of this firmware running on Pocket SDVX Pico, purchasable at https://discord.gg/MmuKd73XbY
|
|
|
|
|
|
|
|
Currently working/fixed:
|
|
|
|
- Gamepad mode - default boot mode
|
|
- NKRO Keyboard & Mouse Mode - hold first button(gpio4) to enter kb mode
|
|
- HID LEDs with Reactive LED fallback
|
|
- ws2812b rgb on second core
|
|
- 2 ws2812b hid descriptor zones
|
|
- sdvx/iidx spoof - Tested on EAC - checkout branches release/pocket-sdvx-pico or release/pocket-iidx
|
|
- 1000hz polling
|
|
- Reversable Encoders with debouncing
|
|
- Switch and LED pins are now staggered for easier wiring
|
|
- Fix 0-~71% encoder rollover in gamepad mode, uint32 max val isn't divisible evenly by ppr\*4 for joystick - thanks friends
|
|
- HID LEDs now have labels, thanks CrazyRedMachine
|

TODO:
|
|
|
|
- store configuration settings in a text file? consider implementing littlefs https://github.com/littlefs-project/littlefs https://www.raspberrypi.org/forums/viewtopic.php?t=313009 https://www.raspberrypi.org/forums/viewtopic.php?p=1894014#p1894014
|
|
- Store last mode in flash memory https://www.raspberrypi.org/forums/viewtopic.php?t=305570
|
|
- debounce on switches
|
|
|
|
How to Use:
|
|
|
|
- For basic flashing, see README in build_uf2
|
|
- Otherwise, setup the C++ environment for the Pi Pico as per https://datasheets.raspberrypi.org/pico/getting-started-with-pico.pdf
|
|
- Build pico-examples directory once to ensure all the tinyusb and other libraries are there. You might have to move the pico-sdk folder into pico-examples/build for it to play nice.
|
|
- Move pico-sdk back outside to the same level directory as Pico-Game-Controller.
|
|
- Open Pico-Game-Controller in VSCode(assuming this is setup for the Pi Pico) and see if everything builds.
|
|
- Tweakable parameters: Pinout, bindings in pico_game_controller.c, USB device reporting as SDVX/IIDX(con_mode) in usb_descriptors.c
